前言

工作中，使用利用spring aop 切面的方式记录日志

一、引入依赖

               
    
     org.springframework.boot
                
    
     spring-boot-starter-aop
            
   

二、项目结构

三、注解类

@Target({
   ElementType.PARAMETER, ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface AuditLog {
       String title() default "";    String desc() default "";}

四、切面类

@Aspect@Componentpublic class AuditLogAspect {
       private static final Logger log = LoggerFactory.getLogger("audit_log");    public AuditLogAspect() {
       }    @Pointcut("@annotation(com.cch.auditlog.common.auditlog.AuditLog)")    public void logPointCut() {
       }    @AfterReturning(            pointcut = "logPointCut()"    )    public void doAfterReturning(JoinPoint joinPoint) {
           this.handleAfterLog(joinPoint);    }    @Before(value = "logPointCut()")    public void doBefore(JoinPoint joinPoint) {
           this.handleBeforeLog(joinPoint);    }    @AfterThrowing(            value = "logPointCut()",            throwing = "e"    )    public void doAfterThrowing(JoinPoint joinPoint, Exception e) {
           this.handleAfterThrowingLog(joinPoint, e);    }    private AuditLog getAnnotationLog(JoinPoint joinPoint) throws Exception {
           Signature signature = joinPoint.getSignature();        MethodSignature methodSignature = (MethodSignature) signature;        Method method = methodSignature.getMethod();        return method != null ? (AuditLog) method.getAnnotation(AuditLog.class) : null;    }    private void handleBeforeLog(JoinPoint joinPoint) {
           try {
               AuditLog controllerLog = this.getAnnotationLog(joinPoint);            if (controllerLog == null) {
                   return;            }            log.info("before ----> title:{}, desc:{}", controllerLog.title(), controllerLog.desc());        } catch (Exception var10) {
               log.error("operlog exception:{}", var10);        }    }    protected void handleAfterLog(JoinPoint joinPoint) {
           try {
               AuditLog controllerLog = this.getAnnotationLog(joinPoint);            if (controllerLog == null) {
                   return;            }            log.info("after ----> title:{}, desc:{}", controllerLog.title(), controllerLog.desc());            return;        } catch (Exception var10) {
               log.error("operlog exception:{}", var10);            return;        }    }    protected void handleAfterThrowingLog(JoinPoint joinPoint, Exception e) {
           try {
               AuditLog controllerLog = this.getAnnotationLog(joinPoint);            if (controllerLog == null) {
                   return;            }            log.info("发生异常:{}", e.getMessage());        } catch (Exception var10) {
               log.error("operlog exception:{}", var10);        }    }}

五、启动springboot 测试

AopTestController

@RestController@RequestMapping(value = "/aoptest")public class AopTestController {
       @AuditLog(title = "标题",desc = "牛逼的方法")    @RequestMapping(value = "",method = RequestMethod.GET)    public void aopTestMethod(){
           System.out.println("哈哈哈");    }}

结果如下：

总结

本篇只是写个简单的demo示例，大家可以根据该工程结合自身公司业务场景进行扩展
